As with many rare bugs ranging from Cicadas to Moths, the Jewel Beetle can be caught while resting on the face of a tree trunk belonging to any random tree planted throughout your Town. Since they are quite sensitive to noise, they have to be approached with caution and care before the deciding swipe of your Net is made.

The Japanese name for the jewel beetle inspired their word for iridescence. Makes sense, I suppose... Since the beetles keep their color after death, it's said their bodies were worn as jewelry long ago. Do you suppose they left the legs and antennae on the bodies when they wore them? ...Blech.

In real life, the Jewel Beetle is a certain species of beetle native to Japan which use the bright, radiant colours of their protective shell in order to overwhelm and scare off persistent predators such as birds.
